In a linear stapled technique for laparoscopic gastric bypass, after the retrocolic and mesocolic windows are created, the omentum and transverse colon are reflected cephalad and the ligament of Treitz is identified and run for distance of _______, at which point it is divided with an endoscopic linear stapler.
A) 45 cm
B) 40 cm
C) 35 cm
D) 65 cm
B) 40 cm
In a linear stapled technique for laparoscopic gastric bypass, the Roux limb is typically run for a distance of __________, at which point a jejunojejunostomy is created between the Roux and the biliopancreatic limbs by first opening each limb with electrocautery shears, and then placing a laparoscopic linear stapler (60 mm) within and deploying.
A) 100-150 cm
B) 100 cm
C) 150-200 cm
D) 75 cm
A) 100-150 cm
True or False. In a linear stapled technique for laparoscopic gastric bypass, the Roux limb is placed through the mesocolic window in a retrocolic antegastric fashion with care taken to avoid twisting or kinking of the mesentery in preparation for the gastrojejunostomy.
True
In a linear stapled technique for laparoscopic gastric bypass, the Roux is oriented to the ___________ wall of the gastric pouch with interrupted absorbable sutures. An enterotomy and gastrotomy are performed on the Roux and the gastric pouch, respectively. The anastomosis is created by deploying and endoscopic linear stapler.
A) Posterior
B) Anterior
C) Medial
D) Lateral
A) Posterior
True or False. The Roux limb may be brought cephalad in a retrocolic or antecolic fashion, and should reach the upper abdomen without tension.
True
True or False. The Roux limb may be brought cephalad in a retrocolic or antecolic fashion, and should reach the upper abdomen without tension.
True
In the transoral approach to laparoscopic gastric bypass, the DST Series EEA OrVil device in the size of a _______ EEA anvil is passed down the patient’s esophagus to the gastric pouch by the anesthesiologist or an assisting surgeon.
A) 28 mm
B) 29 mm
C) 25 mm
D) None of the above
C) 25 mm
True or False. Leaks at the gastrojejunal anastomosis are perhaps the greatest technical complication when performing bypass surgery.
True
In a sleeve gastrectomy, dissection starts at a vessel-free space close to the stomach along the _________.
A) lesser curvature
B) hilum of the spleen
C) greater curvature
D) None of the above
C) greater curvature
True or False. Starting 6 cm from pylorus ring on the greater curvature, a linear cutting stapler divides the stomach aiming somewhat left of the angle of the stomach. Most antral part of the stomach is left in situ.
True
It is recommended to use at least two __________ reloads for ________ tissue at the lower part of the stomach, since the stomach wall is thicker.

B) 45 mm, medium to thick
C) 45 mm, vascular
D) 60 mm, thick to extra-thick
D) 60 mm, thick to extra-thick
True or False. Buttress on the stapler may not decrease the risk of leakage and bleeding from the staple line.
False
